发明名称 System to avoid icing in the discharge piping of a pressure relief valve
摘要 Apparatus for deicing the discharge gas from a safety relief valve includes a high pressure probe and an injection probe extending into the flow path of the discharge gas. Inlet orifices in the high pressure probe include inlet orifices facing directly upstream relative to the gas for communication of the total pressure of the flowing gas to the inside of a reservoir containing the deicing agent. The injection probe connects with an outlet of the reservoir and includes outlet orifices facing directly downstream of the discharge gas flow so that the reservoir is subjected to a driving pressure derived from the difference between the total pressure of the flowing gas and its reverse dynamic pressure. An adjustable connector mounting the high pressure probe in the discharge flow path of the gas allows the inlet orifices to be selectively oriented between positions facing directly upstream and perpendicular thereto to selectively vary the driving pressure.
